Re: [Xen-devel] Dear Tobias Geiger, I Need Help with Xen VGA Passthrough to Windows 8 Consumer Preview / XP (Xen 4.2-unstable)

Dear Tobias Geiger,

One final request from me: Can you check whether the Xen VGA Passthrough patches hosted at David TECHER's official blog are the same as yours?

David Techer told me it's a NVIDIA driver issue, which I don't think so. I seriously wonder what's wrong with the glitch. I am using NVIDIA driver version 296.17 for Windows 8 Consumer Preview.

Xen VGA Passthrough to Windows 8 Consumer Preview: I can watch Youtube videos with audio/sound and surf the internet as well. But I just can't run 3d graphics benchmarks. Only 2d graphics benchmarks can be run.

By the way, I have only recently bought this Palit NVIDIA Geforce 8400 GS at SGD$44. If I buy an ATI card, what would you recommend that is CHEAP? Must be PCI Express x16. Then do you think the Xen VGA Passthrough patches are necessary any more?

Please refer to the computer hardware pricelist here http://www.fuwell.com.sg/uploads/misc/Fuwell240312.pdf and recommend me a cheap ATI card. Preferably SGD$50.

Finally, Xen VGA Passthrough to Windows XP Home Edition also has the yellow exclamation mark glitch with NVIDIA Geforce 8400 GS. With Xen 4.2-unstable.

Thank you very much.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)

Hi Teo,

sorry to hear that it didn't help.

Unfortunatly thats all the hints i'm able to give you - from now on you're out
there alone so to speak :)

Good luck - or (even on the danger of repeating myself:) just buy an ATI

Dear Tobias Geiger,

Thank you for reading through my Xen VGA Passthrough Version 1.6

I am now trying out your suggestion, i.e. expose the 4th memory range.
When I refer to David Techer's official blog and his emails, he only
mention the first 3 memory ranges. When I asked David Techer what
about the 4th memory range, he said nothing.

Let's hope I get lucky and get the yellow exclamation mark with NVIDIA
Geforce 8400 GS (ie Xen VGA Passthrough to Windows 8 Consumer Preview
*PARTIAL* success) FIXED.

By the way, what is the problem with my Xen WIKI? Xen.org
administrator Mr. Lars Kurth edited my Xen Wiki pages for me.

If it works, I will have Xen VGA Passthrough Version 1.7 documentation
and FINAL as well.

Thank you very much for reading through my documentation and giving me
suggestions. I hope it works now.
Dear Tobias Geiger,

I have just exposed the 4th memory region, patched dsdt.asl, recompiled
and reinstalled Xen 4.2-unstable but IT STILL DOESN'T WORK. There is
still a yellow exclamation mark besides NVIDIA Geforce 8400 GS in Xen
VGA Passthrough to Windows 8 Consumer Preview.

I still cannot run 3d graphics benchmarks. Only 2d graphics benchmarks
can run.

Please read through my Xen VGA Passthrough Version 1.6 documentation
again to see if there are any mistakes. Please. Please. Please. I want
to fix that glitch. Any more ideas?

I hope some expert engineers at Intel Corporation (Han Weidong, Zhang
Xiantao, and Ren Yongjie) can fix this glitch with Xen VGA Passthrough
to Windows 8 Consumer Preview. They are after all the original
authors/developers who wrote the Xen VGA Passthrough patches. But Han
Weidong has left Intel Corp, I think. He was still at Intel 3 years ago.

Thank you very much. Eagerly awaiting your reply.
